What factor affects the density of seawater?
The density of seawater depends on temperature and salinity. Higher temperatures decrease the density of seawater, while higher salinity increases the density of seawater. The following figure shows how density is affected by temperature and salinity.
How does the salinity of seawater affect its density?
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.
How is density affected by salinity?
The more salt there is dissolved in the water, the greater its salinity. When comparing two samples of water with the same volume, the water sample with higher salinity will have greater mass, and it will therefore be more dense.
What are two factors that affect the salinity of ocean water?
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
What two factors influence seawater density and which one has the greater influence on surface seawater density?
What two factors influence seawater density? Which one has the greater influence on surface seawater density? Temperature and salinity affect density. Temperature has the greater influence on surface density.
What factors affect salinity?
Factors that Control Salinity
- Evaporation.
- Precipitation.
- The Influx of River Water.
- Atmospheric Pressure and Wind Direction.
- Circulation of Oceanic Water.
What are two factors that control the concentration of salts in seawater?
3 0 out of 2 points Evaporation and temperature are the two factors that control the concentration of salts in seawater.
What factors affect density?
The size, mass, and arrangement of atoms affect the density of a substance. How might these factors work together to cause a substance to have a high density? A substance with smaller more massive atoms that are close together is going to have a higher density.
Which two changes would increase the density of ocean water?
The two main factors that affect density of ocean water are the temperature of the water and the salinity of the water. The density of ocean water continuously increases with decreasing temperature until the water freezes.
What are factors that affect salinity?
Factors that Control Salinity
- Evaporation.
- Precipitation.
- The Influx of River Water.
- Atmospheric Pressure and Wind Direction.
- Circulation of Oceanic Water.
What are two factors that control the salinity of seawater quizlet?
Precipitation and evaporation are the two factors that control the salinity of seawater.
What factors influence density in seawater quizlet?
The temperature and salinity of seawater influence its density. Temperature and salinity vary with latitude. Therefore, the density of seawater also varies with latitude.
What two factors will increase the density of ocean water?
The two main factors that affect density of ocean water are the temperature of the water and the salinity of the water. The density of ocean water continuously increases with decreasing temperature until the water freezes. Ocean water, with an average salinity of 35 psu, freezes at 28.5oF (-1.94oC).
What factors affect the salinity of seawater?
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
What are the causes of the salinity of seawater?
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.
Which of the following has the greatest influence on seawater density?
That leaves temperature and salinity as the primary factors determining density, and of these, temperature has the greatest impact (Figure 6.3. 1). Figure 6.3. 1 Global sea surface density.
What happens to seawater as density increases?
Temperature changes effect seawater density: as water cools its density increases. As water cools, H2O molecules pack more closely together (because the molecules are vibrating less at lower temperatures) and take up less volume.
What are two ways to affect the density of water?
Factors affecting Water Density There are two factors which are affecting the density of water, namely, temperature and purity. In the case of pure water, temperature plays a crucial role. The density of water varies with temperature but not in a linear way.
What factors cause differences in density?
A density difference can exist between two fluids because of a difference in temperature, salinity, or concentration of suspended sediment. Density currents in nature are exemplified by those currents that flow along the bottom of oceans or lakes.
What two factors control the salinity of seawater?
The salinity of water in the surface layer of oceans depend mainly on evaporation and precipitation. Surface salinity is greatly influenced in coastal regions by the freshwater flow from rivers, and in polar regions by the processes of freezing and thawing of ice.
What two factors influence seawater density which one has the greater influence on surface density?
Which one has a greater influence on surface seawater density? Salinity and temperature. Temperature has the greatest influence because variations in surface temperature are greater than salinity variations.
What are some factors that impact the salinity quizlet?
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
What factors affect the density of ocean water quizlet?
What 2 factors affect the density of ocean water? Temperature and salinity. The ocean is least dense in the surface zone, where it was warmest. However, higher salinity also increases density.
How does temperature and salinity affect the density of ocean water?
Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water.
What are the two factors that control the concentration of salts in seawater?
3 0 out of 2 points Evaporation and temperature are the two factors that control the concentration of salts in seawater.
What two factors influence seawater density which one has the greater influence on surface seawater density quizlet?
What two factors influence seawater density? Which one has a greater influence on surface seawater density? Salinity and temperature. Temperature has the greatest influence because variations in surface temperature are greater than salinity variations.
What are the two primary ways to increase the density of seawater?
The density of seawater can be increased by reducing its temperature, increasing its salinity , or increasing the pressure.
What are the factors affecting density?
Density and temperature As the temperature increases, most materials expand or increase their volume. This results in a decrease in density. Likewise, when the temperature goes down, the density usually becomes greater. For example, at normal atmospheric pressure, air at 0 °C has a density of ρ =1.29 kg/m3.
What are the factors on which density depends?
Answer: Density of an object depends on its mass and the space or volume occupied by it. So mathematically, Density is expressed as D = M/V. or D = M^1.
What is density affected by?
The density of an object can change if either the mass or volume of the object is changed. Fluids, such as water, have a certain density. If an object is more dense than water, it will sink; if it is less dense than water, it will float.
